我正在开发一个带有最新SDK的iOS应用程序.
我已将Landscape右方向设置为可用的唯一方向,我对viewController视图有疑问.
这是我的代码：
- - (void)viewDidLoad
- {
- [super viewDidLoad];
- [[NSNotificationCenter defaultCenter] addObserver:self
- selector:@selector(deviceOrientationDidChange:)
- name:UIDeviceOrientationDidChangeNotification
- object:nil];
- [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
- }
- - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
- {
- return (interfaceOrientation != AVCaptureVideoOrientationLandscapeRight);
- }
- - (void)deviceOrientationDidChange:(NSNotification*)notification
- {
- UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
- if (orientation == AVCaptureVideoOrientationLandscapeLeft)
- NSLog(@"Orientation: Landscape Left");
- else if (orientation == AVCaptureVideoOrientationLandscapeRight)
- NSLog(@"Orientation: Landscape Right");
- NSLog(@"FRAME: %@",NSStringFromCGRect(self.view.frame));
- }
这是我得到的日志：
- Orientation: Landscape Right
- FRAME: {{0,0},{320,568}}
- Orientation: Landscape Right
- FRAME: {{0,568}}
我的问题是关于{{0,568}}：
为什么我会得到这些价值？
我认为正确的值是{{0,{568,320}}.
解决方法
我相信框架不会对方向变化做出反应.
编辑：我原来的解决方案过于复杂,无法满足您的需求.如果您正确找到当前方向,那么只要将您的宽度解释为高度(如果您处于横向模式).
